, ment with the clutch hub 14 or to move the same out of engagement therewith.

A sprocket wheel'l is fixed to the hub of the traction wheel 4 and a sprocket chain 17 is trained around the sprocket wheels 13 and 16 andis adapted to transmit rotary movement from the traction wheel 4 to the i sprocketwheel 13.2'Therefore it will be seen that when the clutch member is moved into engagement with the clutch hub 14 of the wheel13 thatthe shaft 12 is caused to rotate in` unison with the Said sprocket u'heel 13.

A shaft 18 (made up of sections connected together byauniversal joint) is journalcd for rotationat thc side of t-he frame 1 and carries at its rear enda beveled pinion 19 which meshes with a beveled gear wheel 20 ixcd to the end of the shaft 12. The shaft 18 is connected at its forward end with the shaft of a roller 21 which is journalcd in the r casin of a thresher, indicated in general at .Cil

22. his thresher is located at the delivery end of the trunk 5. A trained around the roller 21 and a similar t roller 24 is journaled at the opposite end of the trunk 5. The belt 23 is provided upon its outer face with a series of slats 25 and the upper run of the belt is arranged to travel immediately behind the cutting apparatus of which the guard fingers G and the knife bar 7 form component parts.

A disk 26 is fixed to the forward end of the shaft of the roller 21 and is provided with an eccentrically positioned pin 27. A pitmnn 28 is ivoted at one end upon the pin 27y and at lts other end is pivotally connected with the knife bar 7. Therefore it will be seen that as the roller 21 rotates and i the belt 23 is moved in an orbit the knife bar 7 is reciprocated transversely with relation to the guard fingers 6. Thus means is pro- -vidcd for operating the conveyer belt and the cutting apparatus simultaneously.

The thresher casing 22 is provided -with ka concave 29 .which in turn is provided with teeth 30 of usual pattern. A cylinder 31 is journaled in the thresher casin 22 and is fprovided lupon its periphery with teeth 32 .which are adapted to coperate -with the 'teeth 3Q in knockingthe kernels of grain trom the heads.;

A distributer 33 is journaled in the thresher casingV 22 above the roller 21.v This `distributer isln the form of a blade twisted spirally'andls adapted. toengage the material as it is brought toward the thresher casing: by theconveyerbelt23 and distribute the, same' along the cylinder and concave, therebytpreventin sind-material from beingpresented to t e said .cylinder and concave ata' si1 1gle.'point.'l` Q j t Spaced'n ers 34A are located at the delivery end fof t e concave 29 and are adapted to prevent the straw from falling down upon conveyer belt 23 isa worm auger 35 which is journaled in a trough 36 at the outer end portion of the casing 22.

An elevator trunk 37 is mounted at the delivery end of the threslier casing 22 and is provided with upper and lower crank shafts 38 and 39. Rack bars 40 are mounted upon the cranks of the shafts 38 and 39 and are adapted to reci rocate as the said shafts ro tate, whereby tlie straw deposited upon tht` said bars is elevated and eventually ejected from the upper outer end of the trunk 3T. The shafts ofthe cylinder 31. distributor 3ST and the shaft 38 are provided with sprocket wheels and a chain 41 is suitably trained about the said sprocket wheels so that. tlnx said parts are rotated from the roller 21.

A crossed belt 42 operatively connects the cylinder 31 with the worm auger 35. The rack bars are provided at their lower ends with spaced fingers 43 which assist the tingers 34 in preventing the straw from falling down upon the auger 35. The rear end ot the trough 36 enters the lower end of an elevator trunk 44 in which is mounted a suitable belt elevator of usual pattern (not. shown) and whichis operated by the auger 2&5.

A cleaning fan 45 is mounted upon tho frame 1 and is located below the delivery end of the elevator trunk 44. The shaft4 ot' thefan 45 is provided wit-li a pulley lo and a pulley 47 is fixed to a beveled pinion :t3 which is journaled upon the arm 49 carried by thc frame of the machine. A belt 50 is trained around the pulleys 46 and 47. The pinion 48 meshes with a beveled gear wheel 51 which is attached to the side of the traution wheel 3. The casing of the fan t5 is arranged to deliver the cleaned grain into the elevator trunk 52 which incloses a suitable elevator belt (not shown). The said belt is moved by a pulley 53 which is operatively connected therewith in any suitable manner and which is driven by a crossed belt 54 which also passes around a pulley 55 mounted upon the shaft of the cylinder 31. The fan 45 is located between the traction wheels 3 and 4 and the said fan is provided with a delivery chute 56 which is adapted to receive the unthreshed heads of grain. The said unthreshed heads of grain are adapted to pass alon the said chute and fall upon the outer en of the conveyer belt 23 which will carry the said heads back and pass them again through the said threshing mechanism.

The elevator trunk 52 has its delivery end disposed overa platform 57 which is supported beyond the outer side of the traction wheel 3 Vand -upon this platform bags or other suitable receptacles .may be provided for the reception ofthe grain as it is delivered from the trunk 52.

The forward end of a tongue 58 is conY nected with the axle 2 and the rear end ot i) fi the said tongue is supported by a caster wheel 59.-,fAn `operators platform 460 is mounted fguponz .the yrear portion of the tongue'i'fand 'a tiller 6l is 'located above the 4said-"zplatform Aand is 'connected with the shaftjof .the vframe in which the whee1'59 is journaled-.z-fAn operators'seatGQ is mounted upon the said tiller. As the machine is passing fover..:thefground .the operator pulls the tillcrflf hetave'en'his legsand by swaying his body toone iside or' the other the frame of theicalsterwheel 59 isswune` so that the machine may be'l guided over the ground.

Aftree 631s supported -at the rear end portion of`tlie tongue 58 :and carries Yat -its end portions doubletrees 64 which in turn support swingletrees 65. lIt is to these swingletrees that .the draft'animals are attached and 1 they are arranged with one pair at each side of the tongue 58. y
